Application filed September 7, 1912,,serie1 NO. 719,080. Renewed October5, 1916. Serial Ne.'12e,946.

To all whom it may concern:

Be it known that I, Lou s KOSSUTH J OHN- SON, a citizen of the UnitedStates, and a resident of the borough of Brooklyn, county of Kings, andState of New York, have invented certain new and useful Improvements inCompositors Type-Setter Channels, of which the following is aspecification.

My invention is designed to afford a type containing channeland a typecolumn support from which the types may be quickly and convenientlyremoved by and between the compositors thumb and finger o'r fin gers, ashereinafter set forth. i

This invention consists essentially of "a pivotally supported typecontaining channel in conjunction with a typecolumn support formed witha cut oif shoulder which separates the lowest type fromthose in thecolumn above when the channelis pushed backward against the resistanceof resilient means by which the channel'is automatically returned to itsnormal position when released by the act of withdrawing said lower type.

In the accompanying drawings,

Figure 1, is a front view of the upper and lower portions of a typesetter channel and support, made in accordance with my invention' Fig.2, an elevation taken at right angles to Fig. 1;

Fig. 3, is a horizontal section taken upon plane of line 3-3 Fig. 1,with the type containing channel in its normal posltlon- Fig. 4, is asection similar to Fig. 3, s owing the type containing channel swungback to give access to the lowest type on the typesupporting surface;

Fig. 5, is a view similar to Fig. 2, showing the type containing channelpushed back and indicating in dotted lines the method of grasping thelowest type between the thumb and finger.

Fig. 6, is a horizontal section taken upon plane of line 66 Fig. 1.

My improved composltors type channel and support may be used singly forspecial types, spaces, &c., as an ad unct to the usual case, or a seriesmay be combined and built up into a complete compositors type caseaccommodating all thedenominations of a font of type. r e The type aredistributed into the contain-' ing channel-C, by automatic machinery orby hand as may be found most expedient.

The distinctive v feature of'the present in-' vention consists-inpivotally supporting the type containing channel over a type floorformed with an off-set or step which separates the lowest type in thecolumn from parts shown in the accompanying drawings,

which however illustrate "a practical embodiment of the essentialfeatures of my invention.

The type containing channel C, is piv- Otally supported, on one of itslongitudinal sides or edges, between stationary parts, by any well knownmechanical expedients; as by forming the channel with end trunnions c,c, fitting in sockets formed for their reception in stationary parts ofthe frame A. The lower end of the channel C, is open, and the column oftype contained therein is supported upon a stationary type floor 7,which is formed with an; off-set step f, upon which latter the lowesttype t, in the column, rests when the channel is in its forward ornormal position, with the front of.

the channel bearing against the stop a. The

channel C, is held normally against this detached from the main column.The step f, itself is relatively thin and tapered in cross section, andis of less length than the type, so as to expose the under side of thefront end thereof to the thumb.

The operation is simple and as follows. The compositor presses back thepivotally supported type containing channel by means of his indexfinger, or second finger,

or both, thereby pushing all but the lowest type in the column over ontothe upper type supporting surface 7, and leaving the lowest type on theoff-set step 7, positioned between the fingers and thumb of thecompositor, who is thereby enabled to grasp and remove said lowest typelaterally by a simple movement of the hand. On the release of thechannel the spring returns it automatically to its normal position withthe column of type again resting upon the step 7. I

The advantage of this arrangement is that the compositors thumb indetaching a type does not have to overcome the resistance of the wholeweight of the type column as in the structure set forth in my formerLetters Patent No. 230,784, dated August 3rd, 1880, in which theconsequent strain and wear upon the thumb became serious obstacle to theadoptionof this class of compositors type case on a commercial basis,

my present invention I obviate this difficulty since the detached typerest free Copies of this patent may be obtained for upon the deliverystep 7, and are removed while the weight of the column is sustainedtemporarily by the upper type supporting surface f.

What I claim as my invention and desire to secure by Letters Patent is,

A type setting device of the character designated, comprising an,upright typecontaining channel pivotally supported longitndinally at itsspine, a stop for holding said channel in its normal position, elasticresilient means which tendv constantly to press said channel againstsaid stop, and a stationary type supporting floor underneath saidchannel formed with a rear surface adapted to close the lower end of thechannel and support the column of type thereon when the channel is swungback laterally and with a front delivery step or off-set adapted tosupport the types when the channel is in its forward normal position,said off-set between the two said type supporting surfaces constituting.a means of detaching the lowest type in the column when the channelis'pressed backward laterally against the resistance of said elasticresilient retraotile means, for the purpose described;
